How do I use Intel TBB with CMake?

To use Intel TBB with CMake, you need to find the TBB package and link it to your project. You can do this by adding the following lines to your CMakeLists.txt:

find_package(TBB REQUIRED)

add_executable(my_app main.cpp)
target_link_libraries(my_app TBB::tbb)

What if I installed TBB in a custom directory?

If TBB is installed in a custom directory, you can specify the path using the CMAKE_PREFIX_PATH variable when running CMake:

cmake -DCMAKE_PREFIX_PATH=/path/to/tbb ..

Are there any specific compiler flags I should use?

Yes, you might want to use optimization flags like -O2 or -O3 for better performance. Additionally, ensure you are using the correct C++ standard, such as -std=c++11 or later.

Can you give me an example of a simple TBB program?

Sure! Here's a simple example that uses TBB to parallelize a loop:

#include <tbb/tbb.h>
#include <iostream>

int main() {
    tbb::parallel_for(0, 100, [](int i) {
        std::cout << "Processing " << i << std::endl;
    });
    return 0;
}
